I cannot add another printer

I have installed INTELLIscribe and set up a virtual printer port. If I install a printer and assign it to the INTELLIscribe port and finish it, then try to add another new printer, Windows tells me that I haven't finished installing the first printer.

This problem, though annoying, is not a fatal error. It has been encountered only if certain print drivers are used in conjunction with INTELLIscribe. The problem is resolved when the system is restarted.

The error is present due to interaction between the print driver and the spooler at the point of printer install only. The spooler tries to gather some driver/vendor specific information from the printer, which is not supported by INTELLIscribe
